Newly purchased automobile tires of a certain type are supposed to be filled to a pressure of 30 psi. Let μ denote the true average pressure. Find the P-value associated with each of the following given z statistic values for testing H0: μ = 30 versus Ha: μ 30 when σ is known. (Give the answers to four decimal places.) (a) z = 2.20 P = (b) z = -1.65 P = (c) z = 0.51 P = (d) z = 1.44 P = (e) z = -4.25 P =
